6 Claims. (01. 156-33) This invention relates to the general art of cur- Fig. 2 is a top plan on an enlarged scale, viewe tain fixtures, and has reference more particularly on the line 22 of Fig. l. to devices that are attached to the vertical side Fig. 3 is a perspective group view, showing the members of a window or door frame and serve parts of the ornament fastening in endwise sepah the purpose of supporting the curtains in parted rated relation. relation, the lower portions of the curtainsbeing 4 is a cross-section on the line 4-4 of gathered and hung over the hold-back brackets Fig. 2, a from which they are suspended at opposite sides g- 5 is a DBFSDBCUVB V illustrating a od of the window or door. 7 form of one of the ornament fastening parts.

The ornament is of highly frangible maspot welded to the front side of the limb 15 a terial, and it frequently happens that in tighten- F 5 plate i5 0f wnsiderably g a e Width ing the bolt the glass of the ornament is splintere'd than the limb l5. Loosely embracing the limb or cracked, i t region of th b r h l d i5 and presser plate It is a collar preferably havsometimes the stem or shank of the ornament is his the form best shown in Figs. 3 and 4 and 30 completely broken off. This is due mainlyto the comprising a back plate ll, forwardly projecting fact that the pressure of the bolt head is localized e fl e and i -turned l ps I9 on the free in t region of t 1 1 hole, vertical edges of the'fianges l8; all these parts It is the main object of the present invention to beingintegrai. In the b plate I? is a e tral provide an improved fastening for the ornament pped ole 20 adapted to receive a thumb screw 35 that will entirely eliminate this danger of splintering, cracking and breaking the ornament and d a es the glass ornament, the lower end the waste consequent thereon, and this object is D -D O Which is Slightly narrowed to fit attained by an improved construction by which between the side flanges l8 of the collar, as shown 40 the damping pressure is if mly distributed in Fig. 4.. After the collar has been slipped down 40 over the entire area of the portion of the ornathe Presser Plate i limb the uppermmt engaged by the metal shank member end portion of the latter is bent rearwardly to Another object of the invention is to provide a Sign lug zsiwhmh overhes w upper edge an improved ornament holder that will effectively back plate of the Collar and locks the prevent any side play of the ornament relatively to gs ggi igizg gg zi ii wise secured to the outer face of the lower curved v portion M of the shank member of the bracket Elven (71011 is illustiated 1n the accomp abuts at its upper end against thelower ends of il i fii a g gje ation f porti n f qid the flanges i8, and thus locks the collar against 50 e. S I1 6 0 a 0 0 a 9 displacement in a downward direction. In member of a window frame and a curtain, showmounting the ornament on its supporting shank ing my improved hold-back bracket attached to member, the collar having been assembled and the frame, and the curtain gathered and hung locked in place, the thumb screw 2| is backed oil, over the bracket. and the shank 22 of the ornament is inserted in 55 tion. A lower stop lug 24 spot welded or otherlatter against displacement in an upward direc 45 the collar between the presser plate I6 and the lips IQ of the flanges. The thumb screw is then tightened, which clamps the shank 22' securely in the socket thus formed. The pressure of the thumb screw is transmitted through the entire area of the presser plate 16 to the substantially co-extensive area of the rear side of the shank thus avoiding any tendency to fracture, crack or break the shank 22. At the same time, the side flanges 28 very securely support the ornament against any lateral looseness or side play. If a new ornament is to be substituted, a mere backing on of the thumb screw 2| is all that is necessary to withdraw the old ornament and substitute the new one.

In Fig. 5 I illustrate a slight modification, wherein the presser plate I6, instead of being a separate element spot Welded to the limb I5, is made as a widened portion of said limb coextensive in area with the presser plate it. This construction is slightly simpler than that of Figs. 1-4 but is slightly more costly than the latter, for the reason that the waste of metal involved in making the structure of Fig. 5 more than balances the slight additional cost of making and attaching presser plate l5. It will be evident that in the structure of Figs. 1-4 the entire shank member l2, i l, MS can be cut in suitable lengths from a continuous strip of, sheet metal, and bent to shape; whereas the structure of Fi 5 requires a strip of metal the full width of the presser plate I6, with the excess width cut off and discarded in all except th presser plate region. The operative principle of Fig. 5, is however, identical with that of Figs. 1-4, and is fully within the purview of the invention as defined in the claims.

Changes and modifications in the details of structure and arrangement may be resorted to within the scope and coverage of the claims.

I claim:

1. A curtain hold-back bracket, comprising a metal shank member adapted to be attached at its upper end portion to a side member of a window or like frame and formed with a forwardly projecting U-shaped lower end, a clamp collar loosely embracing the front limb of said lower end and having a tapped hole in its rear side, a frangible ornament having its lower end portion inserted between said collar and said front limb, and a clamp screw engaged with said tapped hole and bearing against the rear side of said front limb.

2. A curtain hold-back bracket, comprising a metal shank member adapted to be attached at its upper end portion to a side member of a window or like frame and formed with a forwardly projecting U-shaped lower end, a clamp collar loosely embracing the front limb of said lower end, said collar comprising a back plate having a tapped hole therein and integral forwardly projecting side flanges formed with inwardly turned lips, a frangible ornament having its lower end portion inserted between said lips and said front limb, and a clamp screw engaged with said tapped hole and bearing against the rear side of said front limb.

3. In combination with the subject-matter defined in claim 1, upper and lower stops on the U- shaped lower end of the shank member overlying the upper and lower edges of the collar to confine the latter against vertical displacement.

4. In combination with the subject-matter defined in claim 2, a rearwardly extending stop lug on the upper end of the front limb of the U- shaped lower end of the shank member overlying the upper edge of the collar, and a stop member on the lower portion of said front limb underlying the lower edges of the side flanges of the back plate.

5, A specific embodiment of the subject-matter defined in claim 1. wherein the metal shank member is narrower than the lower end portion of the ornament, and a presser plate of a width equal to the width of the lower end portion of the ornament is secured to the front side of the front limb of the U-shaped lower end of the metal shank member to transmit the thrust of the clamp screw to the entire area of the ornament engaged by said presser plate.

6. A specific embodiment of the subject-matter defined in claim 1, wherein all of the metal shank member except the portion embraced by the colis narrower than the lower end portion of the ornament, and the said portion embraced by the collar has a width equal to the width of the lower end portion of the ornament, whereby the thrust of the clamp screw is transmitted to the entire area of the ornament engaged by the said widened portion of the shank member embraced by the collar.
